BOOM ATTACHMENT FOR TRACTORS Filed April 1'7, 1930 2 Sheets-Sheet 2 cant has been able to ascertain are braced or i Patented Apr. 26, 1932 UNITED STATE MAGNUS BERG, OF CUSHING, OKLAHOMA BOOM ATTACHMEN 1 FOR TRACTORS Application filed April 17,

My invention relates to hoisting booms, and more particularly to booms for attachment to tractors and other vehicles, particularly those used in pipe line work.

i The objects of my invention are to provide a device of this class which is new, novel, practical and of utility; which may be easily and quickly attached; the weight of which will be supported directly upon the frame of the vehicle; which will require no more width in road clearance than the vehicle upon which it is attached; which will function regardless of the depth to which the vehicle treads may become sunk in soft earth; which will be strong and durable; which may be attached upon the front, rear, or either side of the vehicle; which will lift more weight than the usual tractor boom attachment under similar conditions; and which will be eflicient in accomplishing allthe purposes for which it is intended.

There are at the present time a number of boom attachments for vehicles in use, but so far as applicant knows or can ascertain there are objectionable features embodied in each and all of them. All, within applicants knowledge are attached outstanding from the vehicle, and sufficiently near the ground to cause considerable trouble when the vehicle is working in soft earth. Many times it becomes necessary to remove the boom entirely from the vehicle in order that it may proceed.

Another serious trouble encountered with the vehicle boom attachments of present use, is their damage to the vehicle power plant. All of them at present so far as this applisupported upon the vehicle power plant instead of upon the vehicles chassis. In using this mode of supporting or bracing the boom, there have been many instances in which the power plant has been broken, and times when it has been twisted entirely out of the vehic-le frame.

Applicants device does not in any manner hamper the progress of the vehicle. It is supported upon the chassis of the vehicle and thus is noninjurious to the power plant. It overcomes many of the impractical features of the counter balance of my invention and 1930. Serial No. 444,899.,

of devices of this class now in use, as well as accomplishing many new and novel results of its'own.

l/Vith these and other objects view as will i more fully appear, my invention consists in the construction, novel features,and combination of parts hereinafter more fully described, pointed out inthe claims hereto'appended, and illustrated in the accompanying;

pivotal connection which is typical through- ,7

out the device; 1

Fig. 5 is a side elevational view ofa slightly difl'erent embodiment of the. organization shown in Fig. 4; and,

Fig. 6 shows front weights.

Like characters of referencedesignate parts in all the figures.

It is understood that various'changes in the form, proportion, size, shape, weight and like . other details of construction, within the scope of my invention may be resorted towithout departing from the spirit or broad principle V without sacrificing any of the advantages th derstood that the drawings are to be interpreted as being illustrative and not restrictlve.

The device as heretofore described is adapted for attachment upon any vehicle, but is illustrated andwill be described herein as being disposed upon a caterpillar tractor having a front axle 1, and a rear axle 2, each supported by a pair of front wheels 3 and rear wheels 4. ;A pair of caterpillar treads 5 and 6 are mounted upon said wheels and are adapted to be driven by said wheels which are in turn driven by apower plant, not. shown, but the radiator of which is shown at 7. Upon the outer ends of each of said axles l and 2,; is one of a pair of frame members or beams 8 is a side elevational view of the and side views of one ereof; and it is also unupper face of said frame v .r

legs 10 and 11 are preferably spaced equally upon each side of the longitudinal center point of said beam 8. Said legslO and 11 supportupon their upper ends a horizontal pipe or tube 15 which in turn supgports by brackets .30 and 31, a smaller tube .or pipe-16 parallel to saidtube 15. Said tube 15 is further supported braces 17 and .18. desired point upon thefront Attached 'at a end portion of said tube 15 .is -a brace .rod 19 which extends 7 the usual differential housing,

a rod 19 to said across the vehicle :and attaches .aibracket 2O iormedupon said .front axle 1. In crossing the vehicle. said rod 19 passes between the front end ofzthe .power plant andthe rear end .ofsaid radiator. Attached at a desired :point upon the rear :end portion of said tube 1 5 .is a brace rod 21 which may extend to and attach not shown, of the vehicle. or may be attached to said rear attaches said axle 8. The manner in whicla the upper end of said rod l9'isattached to said tube 15 is best seen in Fig. 4, in which abracket22rand a .pin23 act :asa .meansfor making a pivotal attachmerit. The mode of attachment :as shown Fig. 4 is typical with the manner of attaching bracket 20 and also with the manner in which said rod 21 is attached to mid tube .15 and the said housing or rear axle 9. V V A boom mast w38 havingits lower end :bifur- .cated :to form two outspread legs .39 and .24 has the lower .end of said legs attached .to the upper face of said beam .9. attachment .may best be seen in Fig: 5, in which an upstanding bracket '25 and a pivot pin 26 embrace the lower end engaging the usual hoisting tackle, not shown.

The means for adjusting the outward angle at which said mast 38 is disposed, comprises a hollow tube 238 pivotally attached at .its lower end the manner described with reference to Fig. 4, to the longitudinal center point of said tube 15. Said tube '28 at its upper end portion .slidably receives the lower end portion of a smaller tube 29 the upper end of which is connected by a chain link .32 to .an eye 33 in said mast 38. As. may best be seen in Fig. '3, said tube .28 is provided with a plurality'of pairs of .al ined perforations 34$ which .are adapted to receive-a pin 35 therethrough for engaging .alined perfmations .in the lower I therefore consider as my own vehicle diiiferential supporting member,

The manner of of each leg.

Said mast 3.8 has .a plurality lot-eyes 27 for P hlcle, means for bracing said we ght to saidend portion of said tube 29. The positioning of said pin 35 in various selected pairs of said perforations 84, will vary the angle at which said mast is disposed. 1

A plurality of metal weights 36 each having a shaped transverse groove 87 will be supported by said tubes 15 and 16, and will act as a counter-balance tor-the weight of any obje'ct supported by the tackle attached to said mast38.

Should it 'be desired to attach the device in which mast 38 will function from the front of the vehicle, the legs 39 will be attached to said axle 1 members 10 and 11 will be attached to' the-rear axle 2, and the lower ends of said rods 1-9 and 21 will be attached to said axle 2. s V I Applicant believes that by reading the foregoing description the manner of the operation will be obvious, and therefore has not rings and described herein, and applicable for uses and purposes other than as detailed, .and

all such modi- =fications and adaptations and other uses of the form of the device herein described as;

' axle 9 in the. manner in which said rod 19 fairly fall Within'the SCOPQ'O'f m inventive- Having thus described my invention, what is claimed and desired to be secured by Letters Patent, is
